X1900xt/xtx

post #1 of 34
Thread Starter 
I just went on Newegg and I was comparing the X1900XT's and X1900XTX's because I am going to get one soon and I saw that on newegg the ATI and Sapphire XTX has a much higher memory clock speed. Is this a typo, or simply they count the speed differently? But the core clock speed is the same as the others... does ATI and Sapphire XTX have a better card or is just a mistake? The Sapphire XT is correct, it is the same as the Powercolor, but both ATI's and the XTX from Sapphire have a MUCH higher memory clock speed.

The XTX's have twice as high memory clock speed as the XT which doesn't make an sense and the XTX have 1550MHz which the ATI XT has 1450MHz... weird :withstupi The other thing is that the Powercolor XTX has a clock speed of 50MHz faster than the XT which is normal. So shouldn't the other XTX's have 775MHz?

They are just taking into account that it is DDR rates. 775x2 is 1550. They are all pretty much the same.

Its because it is doubled, ddr which means double data rate. One of them was measured with double data rate and the other wasnt.

What are you talking about? O_o. The difference between the XT and XTX is 25/50mhz.

The X1900XTX's have 1.1ns ram timings compared to the x1900xt 1.2ns. Get an XTX it is a better card.

He's talking about this. The memory clocks on the 2 on the right are 2x as high as the power color. It's just counted as DDR with the other 2.

Jori, look at the damn page. The XTX has 1550MHz memory clock speed while the other XTX has 775MHz, (that's double Jori). That's my damn question... Why is it doubled?

He wasn't trying to insult you in anyway. No need to respond to his post in that way, he was just trying to help you out.
